Buddhist-Meditation-Systematic-and-Practical

. In the void body, visualize the three great yogic
channels (to the left, the sasi; on the right, the mihira;
and in the center, the susumna), all seen as void. The
five or seven wheels (cakras) are also visualized and
perceived as void. It is most important to practice with
the median channel and realize its void nature.
Sometimes it is contracted to the fineness of a fiery hair,
and sometimes expanded to a torrent of fire engulfing
the three worlds (see Evans-Wentz).
c. Practice the sunyata meditations of energy-breathing.
During deep breathing, a breath should be held so that
one can correspond its three stages of inhalation,
holding, and exhalation with the three vajra wisdom
syllables: OM—AH—HUM. This should be done very
carefully and must, of course, be very finely
accompanied by sunyata, so that the energy-breath
becomes wisdom-energy. In most books this process is
not given.
Mr. Chen then laughed, asserting, "This is my
pride!"
d. Sunyata of essence. In the Tibetan Vajrayana there
are two sorts of semen, the red (kun) and the white (tha),
hence this practice is known as "kuntha." "Kun" refers
to the five wisdoms and "tha" signifies the essence of
the five elements. When the red one rises, the white
goes down. Together they make Buddhahood, but they
must correspond very exactly to the sunyata of wisdom
